# User Message Hook for Cursor (PowerShell)
# Displays context information to the user
# Maps to claude-mem's user-message-hook functionality
# Note: Cursor doesn't have a direct equivalent, but we can output to stderr
# for visibility in Cursor's output channels
#
# This is an OPTIONAL hook. It can be added to beforeSubmitPrompt if desired,
# but may be verbose since it runs on every prompt submission.
